Patent FR-2144755-A1 (FR)
IPC: G11B20/14
Filed: 1972-07-04
Abstract: A beam addressed optical mass memory utilizes an alterable memory medium which exhibits a change in its optical properties as a function of time or as a function of write-rewrite cycles. A reference bit is recorded on the memory medium and one or more information bits are similarly recorded. The reference and information bits are subjected to essentially the same number of write-rewrite cycles, and therefore exhibit essentially identical changes in optical properties. Information is read out by sequentially directing the light beam to the reference bit and the information bits. A detector produces a reference signal indicative of the intensity of the light beam received from the reference bit and produces information signals indicative of the intensity of the light beam from each of the information bits. The reference signal is directed to a reference channel and temporarily stored. Each of the information signals is directed to an information channel. The reference signal is compared to each of the information signals and readout signals are produced which are indicative of the difference between or the ratio of the reference signal and each of the information signals.

Patent FR-2233528-A1 (FR)
Title: Energy absorber for seat belts - folded strips of material woven into belt rupture in succession
IPC: B60R22/16
Filed: 1973-06-15
Abstract: The folded strips of material are incorporated within a length of belt (16) whose overlapped ends are joined together. The strips and belt pass through a fixed plate (19) and over an upper pin (25) carried by a mounting plate (26). This mounting plate carries a buckle plate (6) with a central aperture. The seat belt passes upwardly from a supply roll through this aperture and around the passenger. The aperture has a fixed pin (20) about which the loop of belt passes and a downward force exerted on the seat belt causes the internal folds to move upwardly into engagement with the edge of the hole through plate (19). Increasing loads cause successive rupturing of the folds to absorb the energy.

Title: Equipment for discharging goods from silos - has horizontal freely pivoting arm eccentrically mounted on driven central disc
IPC: B65G65/48
Filed: 1974-10-15
Abstract: Equipment for agitating and discharging loose goods from silos consisting of a disc centrally positioned on silo bottom and driven about its axis in horizontal plane. Mounted on the top of the disc is an agitating and scraping device which is freely pivoting in horizontal plane about an axis positioned away from the axis of rotation of the disc. With the axis of the agitating and scraping device rotating with the disc the position of the agitating and scraping device above the silo floor level is determined by the relation between the driving torque of the disc and the resistance of the silo contents. The agitating and scraper device is curved with the radius equal to distance between its pivoting axis and the axis of rotation of the disc. In one extreme position it scrapes the whole silo floor when the resistance of the silo contents is minimal and is positioned within the disc surface when the resistance of the silo contents in maximal.

Title: Heat and sound insulating panel of cellular cement or plaster - for outside wall facings, partitions and false ceilings
IPC: E04B1/94
Filed: 1974-11-06
Abstract: Plaster panel contains closed spherical gaseous cells of which the number of dimensions can be controlled during manufacture and which improve the heat and sound-insulating properties and reduce the wt. of the product. When the cells are filled with gaseous CO2 at low pressure, the product obtains fire-extinguishing properties by release of CO2 on rupture of the cells due to the action of heat. The panel is produced by adding to the mixing water 2 pts. by vol. of liquid industrial soap per 1000 pts. water, incorporating a binder, homogeneously mixing the liquid while injecting gas to form a foam, and adding 1 part by vol. of finely powdered plaster per part by vol. of liquid mixture, as measured prior to foaming while mixing slowly and continuously and continuing to inject gas.

Title: Threader with tapered point for false twisting pin - allowing less complex manufacture and greater durability
Inventor: CLAVELET GEORGES
IPC: D02G1/06
Filed: 1975-02-05
Abstract: Threader for passing a textile thread through a false twisting pin comprises a conical filament of deformable synthetic material, pref. polyamide 6.10, which is flattened along part of its length in the wider region, in which it has an eye for passage of the thread, and of which the thin end tapers to a point and is pref. slightly curved. The threader passes through the internal channel of the false twisting pin and can readily pass around the twist locking member in order to emerge on the side of the pin. The threader readily recovers its original shape and does not suffer any permanent deformation, allowing it to be used again a large number of times, due to its flexibility and preservation of quality.

Title: Centrifugal degasser for drilling mud - having rotating bowl to remove sand and integral fan to remove bubbles
IPC: B01D19/00
Filed: 1975-02-25
Abstract: Appts. for degassing and removing sand particles from drilling mud consists of a tank for the mud in which is situated a housing contg. a rotatable hollow body above which is mounted an integral fan impeller. A duct leads from the centre of the hollow body to the fan through which air present in the mud is drawn and thus removed from the system. Heavy sand particles migrate to the walls of the hollow body as it rotates and can be drawn off at the top, while the bulk of the mud leaves via a higher opening. The movement of the mud is caused only by the motion of the hollow sphere and the fan impeller. Appts. is portable and is used for cleaning up during operation the device floats in the mud slurry holding tank.
Patent FR-2302393-A1 (FR)
Title: Automatically lifting toilet seat - with flush handle operating control rod for control of raising spring
IPC: E03D5/04
Filed: 1975-02-26
Abstract: The toilet seat lifts up automatically when the flush is operated and is actuated by pressure being exerted on the flush handle, releasing a joint by means of a control rod. This causes water to leave the tank, which in turn activates a second control rod and then a lever, neutralising a spring. A tenon is then released from a housing surrounding a shaft, this activating the spring to lift the seat.
